The New John Gill Exposition of the Entire BibleJohn 1:24
And they which were sent were of the Pharisees.
] Who were
the straitest sect of religion among the Jews; were very zealous of
the traditions of the elders, and professed an expectation of the
Messiah; and were famous in the nation for their knowledge and
learning, as well as for their devotion and sanctity: and many of
them were in the sanhedrim, as appears from (John 3:1) (Acts 23:6) ,
(See Gill on 3:7).
